BUTTER-TUB CLOSURE.

SPECIFICATION forming part of Letters Patent No. 470,835, dated March15, 1892. Application filed September 4, 1891. Serial No. 404,688. (Nomodel.)

To all whom it may concern.-

Be it known that I, OLIVER DUESLER, a citizen of the United States,residing at Argusville, countyof Schoharie, and State of New York, haveinvented certain new and useful Improvements in Butter-Tubs, of whichthe following is a specification.

Myinvention relates to such improvements;

' and it consists of the novel construction and combination of partshereinafter described and subsequently claimed.

Reference may be had to the accompanying drawings, and the letters ofreference marked thereon, which form a part of this specification.

Similar letters refer to similar several figures therein.

Figure 1 of the drawings is a top plan view of my improved butter-tub orpacking-vessel. Fig. 2'is a side elevation of same, partly in section.

My invention relates particularly to improvements in mechanism fordetachably securing the cover upon a vessel adapted for use in packingbutter or similar substances.

A is the body of the receptacle, made, preferably of sheet metal, andprovided at its up per and lower ends with peripheral flanges or partsin the hoops A A which support the walls of the receptacle. The hoops orflanges may be made of wood or other suitable material.

The cover B is made, preferably, of wood and is provided with adepending flange B, extending around its periphery, which is ofsufficient diameter to permit the flange to inclose the hoop or flange Aon the upper end of the receptacle when the cover is placed upon thesame. The flange B is of such depth that its bottom edge extends almostor quite to the bottom edge of the flange A when the cover is inposition on the receptacle. The cover is provided with a plurality ofclamp-hooks B each hook consisting of a vertical portion B hinged to thevertical edge of the cover by a strap B an arm B projectingright-angularly from the lower end of the vertical portion on a levelwith the bottom of the depending flange B, and an arm 13, projectingsimilarly from the upper end of such vertical portion on a level withthe top of the cover and in the same vertical plane with the lower arm.The clamp-hook is free to rotate in the bearing formed between thevertical edge of the cover and the strap B whereby the arms of the samemay be swung across the periphery of the cover, the dotted curved linesin Fig. 1 indicating the path traveled by the upper arm.

The operation of the device is as follows: The arms of the clamp-hooksare swung without the periphery of the cover and the latter is placedupon the receptacle, with the depending flange on the cover inclosingthe flange A on the covered end of the receptacle. The cover is thensecurely clamped to the receptacle by swinging the clamp-arms within theperiphery of the cover, the upper arm, which may be used as a handle tooperate the device, engaging and seating upon the upper surface of thecover and the lower arm engaging and seating upon the under surface ofthe flange A. I am thus able to easily and quickly secure the cover uponthe receptacle and also leave it free to be de-' tached from the samewhen desired, it being only necessary to swing the clam p-arms withoutthe periphery of the cover, when the latter may be lifted from thereceptacle. Iprefor to provide one arm of each clamp with an inclinedseat, whereby the clamp can be adjusted to compensate for slightinaccuracies in the construction and fitting together of the cover andreceptacle. away a portion of the cover near the edge in the pathtraveled by the'upper arm of the clamp-hook to-form an inclined seat D,upon which such arm rides to its locked position and rests.

I have shown the cover provided interiorly with a packing-ring 0, madeof felt or similar material, to protect the contents of the receptaclewhen closed from the 'air or other foreign matter.

WVhat I claim as new, and desire to secure by Letters Patent, is-

In a packing-vessel, the combination, with I therefore cut a receptacleand a cover for the same, of a clined seat for one arm of the severalclamps,

peripheral flange on the receptacle near its covered end, a plurality ofclamp-hooks severally hinged to the periphery of the cover and eachprovided with an upper arm adapted to seat upon the upper surface of thecover and a lower arm adapted to seat upon the under surface of theflange, and an insuhstantially as described. 10 In testimony whereof Ihave hereunto set my hand this 15th day of August, 1891.
